186 PENNELL: PLANTS OF SOUTHERN UNITED STATES 
EUPLOCA RACEMOSA Rose & Standley 
Dry sandy oak-land, west of Sheridan, Colorado County, 
Texas, September 21, 1913, Pennell 5516. This agrees closely 
with the description of the species of western Texas. It is prob- 
ably most readily distinguished from E. convolvulacea Nutt. by 
its narrower leaves, lanceolate or nearly so in the specimens seen. 
Other Texan collections to be referred here are: San Antonio, 
E. Palmer 889; western Texas, S. B. Buckley. 
VERBENA VENOSA Gill. & Hook. 
Moist soil, Mandeville, St. Tammany Parish, Louisiana,

America; reported from Houston, Texas, and previously collected

The species is widespread and abundant through most of the 
Coastal Plain of the southeastern states, occurring inland in the 
southern Appalachians and westward to Sapulpa, Creek County, 
Oklahoma, Pennell 5390. Two geographical subspecies, which 
seem worthy of recognition, may be distinguished from the typical 
form of the species and from each other by the following key:

viously wider proximally and with definite 
petioles. Corolla conspicuously spotted.
